  Error Message
  WSTRN031: Define both language key and language description
  
  Cause
  This error occurs when you are trying to maintain or create a language entry in SAP (for example, in the language customization or translation settings), but you have provided either only the language key or only the language description, not both.
  
  The language key is a short code (usually 2 characters, e.g., EN for English, DE for German).
  The language description is the full name or description of the language (e.g., English, German).
  
  SAP requires that both fields be filled in to uniquely identify and describe the language.
  
  When does it occur?
  
  When defining or maintaining languages in transaction SMLT (Maintain Language Codes).
  When customizing language settings in IMG (Implementation Guide).
  When importing/exporting translation data and language entries are incomplete.
  When working with translation tools or language-dependent customizing.
  
  
  Solution
  To resolve the error:
  
  
  Enter both the language key and the language description:
  
  Make sure the language key (e.g., EN) is entered.
  Make sure the language description (e.g., English) is also entered.
  
  
  
  Check for completeness:
  
  Do not leave either field blank.
  Both fields are mandatory for the system to accept the entry.
  
  
  
  Use standard language keys where possible:
  
  SAP has predefined language keys; use these to avoid inconsistencies.
  You can check existing language keys in transaction SMLT.
  
  
  
  Save the entry after filling both fields.
  
  
  
  Additional Information
  
  Transaction SMLT: Used to maintain language codes and descriptions.
  Language keys are important for translation and localization processes.
  Incorrect or incomplete language entries can cause issues in translation workflows, message translations, and user interface language settings.
